Characteristic traits of the C-terminal fragment of pepsin

Characterization and arrangement of tryptic fragments from N‐terminal region of hog pepsin

“…The cyanogen bromide hydrolysis of hog pepsin at the methionine residues [1] gives rise to a large fragment which involves the N-terminal half of its chain, lacking arginine and lysine residues [2,3]. For additional specific cleavage it is convenient to aminoethylate the half-cystine residues [4,5] as has been described for the whole pepsin molecule [6].…”
